Ok, I thanks to the previous post, I was able to succesfully define the "id" field in my recipe table. I was then able to create categories on the category/list page. However, when I tried to update the recipes I had created with the categories, the category drop down menu was not there. I tried rewriting my html in my rails\cookbook\app\views\recipe\list.rhtm file and my c:\rails\cookbook\app\views\recipe and I now get the following error


" NoMethodError in Recipe#list"


"You have a nil object when you didn't expect it!
The error occured while evaluating nil.name"


What have I done?


Muchos gracias to those wise soles who can answer these questions. You are truly an unsung hero.
